Software update from Lexus?

Software update from Lexus? (Brake & Gas pedals)

Lexus has said it will introduce a software update that will, if the gas and the brake pedals are pressed at the same time, ignore the gas pedal. When I asked my dealer about this, he said that it will react to even the slightest pressure on both pedals at the same time.

So, my question for you guys is - what's this going to do to the "power launch"? (Rev to 2,000 rpm or so, foot on brake, and release for launch.) If I understand their "fix" correctly, the "power launch" will no longer be possible. Doesn't help left-foot brakers much either.

I gather this new software will be something the owner can decline, but I seriously doubt that will be the case.

Any comments?

My old G35 had a system where its cuts some power when both the brake and throttle are applied. I like the fact that the ISF doesn't have this feature and will make it very well known to the dealer that they do not under any circumstances have my permission to perform this update.
Yeah, I can see this putting a big damper on track days with the F.

I will definitely be watching this thread. I do not want this
software "update" either. Its ok for a Corolla but not the ISF.
I will email my dealer and see what the details are.
That's an answer to a question no one asked. Why fix something that's not broken?

Maybe it stems from all that "unintended acceleration" crap they had with pedals sticking and this is a cover your ass kinda thing?
That's exactly it. The Toyota recall for floor mats, the sticking pedal replacement, the software mod - all for the same thing. The "jammed" gas pedal runaway. The notice came to me from Lexus, not from the dealer.

because some people know nothing about cars and need the poor floor mat installed for them
and if it comes loose
they do not have the ability to rehook it in

So, did the software in the G35 affect your ability to "power launch"? That's my biggest concern about this change.

I figured that was the reason. There's another wave of recalls for the same reason - gas pedal.

It only cut about 30% of the power so it wasn't that bad but still enough to be annoying. I didn't buy my car from Lexus, I bought it through my car broker, I wonder if I'll get a notice?

30% loss when tracking (or similar) is one heck of a loss (in more than once sense of the word).

My recall notice came directly from Lexus Canada
I wonder if they will say something along the lines of "you must accept this update or we will void your warranty" either that or have us sign some kind of waiver releasing them from liability?
Paging Lexus: You have to do something about this craziness. Don't forget that one of the more effective ISF ads is the one showing an F doing a burnout. Many writers even wrote about it. For whatever its worth I think it tickled the fancy of many.
I called Lexus yday about this update. They are fixing the ES series 1st then going to the IS line. The good news is that the re-flash on the computer is indeed something you can opt out of. The rep stated there will probably be 3 components to the recall, new all season floor mats, the reflash and possibly a new and shorter pedal. But you can opt in or out of any component. The shorter pedal is still being debated I was told. So good news, smoky burnouts are still there for us. The rep stated " it is your car, you ultimately have the final say ". A free set of floormats sounds ok to me though.
Thanks, IN Is-F.

It's reassuring to know that it will indeed be optional.

Coming from a BMW, I was suspicious about that claim from my Lexus dealer.
ill take the free floor mats too
hopefully u can pick and choose what u want to take and opt out of
i bet it will be a all or none type deal
Can I keep my old floor mats? I just wanna swap em when they are dirty lol
Just read my newest C&D and there is an article on the ability to safely brake the car from 70 mph to 0 and 100 to 0 and this was done in gear and wot. It only took a few extra feet to stop in a Camrey. They did a G35 too and the G35 will "cut all throttle" when the brakes are applied and the article said Toyota is going this route asap. There goes the launches and burnouts with the brake. Being a government recall I do not know if you can Opt Out but you certainly do not have to respond and bring it in.
